Description

All of these routines write all the characters of the null terminated
character string str on the given window. It is similar to calling
waddch() once for each character in the string. The four routines with
n as the last argument write at most n characters. If n is
negative, then the entire string will be added.

Return Values

All routines return the integer ERR upon failure and an integer value
other than ERR upon successful completion.
